Abstract

The invention discloses a mechanical valve stroke regulating system and belongs to the technical field of mechanical design. The mechanical valve stroke regulating system comprises an intake valve, control cavities, a rotary shaft, a rotary rod, a stretching rod, a spring, a mobile object and a connection pipe. Four cavities are formed in the rotary shaft. Four ribs are arranged in the middle section of the intake valve and distributed in the four cavities of the rotary shaft respectively. One end of the rotary rod is hinged to one end of the stretching rod, and the other end of the stretching rod penetrates through the lower wall of the second control cavity and then is fixedly connected with the lower wall of the mobile object. One end of the connection pipe is communicated with a lower cavity of the second control cavity, and the other end of the connection pipe is communicated with an intake pipe of an engine. According to the mechanical valve stroke regulating system, when pressure in the lower cavity of the second control cavity is high, the middle section of the intake valve rotates clockwise, valve stroke is increased, and air inflow of the engine is increased. The mechanical valve stroke regulating system is reasonable in design, simple in structure and suitable for design of an intake valve stroke continuously variable system.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and specifically relates to a mechanical valve lift adjustment system which can realize continuously variable intake valve lift on the principle of aerodynamics. Background technique [0002] The valve lift of the traditional gasoline engine is fixed and invariable, that is, there is only one cam profile of the camshaft, which makes it impossible for the lift to make the engine respond well in both high-speed and low-speed areas. The valve lift or cam profile design of a traditional gasoline engine is a balanced choice for the engine under all operating conditions. As a result, the engine can neither get the best high-speed efficiency nor the best low-speed torque, but it can get The most balanced performance under all working conditions. The adoption of variable valve lift enables the engine to obtain the required valve lift in both high-speed and low-speed areas, thereby im...
